Kernel-based Virtual Machine (KVM) is a virtualization solution developed by small Israeli software company Qumranet and supported by Red Hat since that company's acquisition in 2008.https://dudodiprj2sv7.cloudfront.net/product-logos/Bd/9w/73TO1VLKWOV6.jpegRed HatGreat Linux-integrated virtualization foundation2017-08-03T20:55:19.292ZI am a consultant who provides KVM-based solutions to customers from all sizes and industries.
At the customers, KVM is usually used by the IT departments, providing virtulization services to all kinds of users, departments and maybe even their customers.
Regarding the business problems KVM adresses:
KVM manages to provide a Linux-integrated virtualization foundation which enables IT departments to provide virtualized systems very fast and efficient. With enough knowledge, IT departments simply install Linux servers and start KVM VMs. The time frame from starting until VMs are up and running is very short, so IT departments don't necessarely have to buy virtualization products if they use KVM.,KVM is really good at providing fast and reliable virtualization for Linux guests
Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools
KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well,KVM itself doesn't ship with a management interface
KVM itself is a bit complicated to handle
KVM needs Qemu to virtualize Windows guests,10,KVM normally enables customers to fullfill their business goals very fast and it is free, so there is a very small time window from implementation to "investment is returned"
If IT staff doesn't have hardcore Linux experience, they will need proper learning time until they'll be able to handle KVM,Xen, Oracle VM VirtualBox, VMware ESXi and VMware Player,Red Hat Ceph Storage, Red Hat Enterprise Virtualization, DockerValentin HöbelKernel-based Virtual Machine is good for virtualization and Openstack services2017-04-27T15:32:35.706ZWe are using Kernel-based Virtual Machine (KVM) as part of our storage solution (OpenStack based). Our solution provides low-cost disk volumes to researchers to use for archiving and data backup. The volumes are provided by KVM virtual machines orchestrated by OpenStack Cinder. It was easier to implement this solution with KVM than XenServer Hypervisor.,Easy way to work with OpenStack
Better performance with the Linux OS
Lowest Cost,Complex networking
GPU processing is not fully supported
It's hard to set up without support tools,8,Capital expenditure costs are low, because is open-source and free
Operational expenditure costs are medium because it's necessary [to have] an IT team with experience in Linux
First step to the virtualization world. Wake up, we are in the 21st century,XenServer and VMware ESXi,VMware ESXi, Apache CloudStack, XenServerStenio Pereira Filho

Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer).

I recommend using KVM if you want to start a proof of concept of OpenStack services because it is very simple to configure and has much documentation about it. If your IT environment is Linux based, KVM is a great alternative to virtualize your infrastructure. It works with Windows virtual machines, but it is better with Linux obviously.
